To a-ZZ whom 'it may concern:

Be it known that I, ANTON BECKER, of Columbus, in 'the county of Franklin and State of Ohio,'have invented certain new and useful Im rovements in ,Underframes Afor Cars; and do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to'which it appertains to make and use the same.

My invention relates to improvenents in car underframes,-the object of the invention being to simplify the construction of underframes for short cars, such as four-wheeled cabooses, and at the same time insure the necessary rigidity and strength of the underframe. i.

lWith this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawin s', Figure 1 is a transverse sectional view il ustrating an underfraine embodyin my improvements, and Figi. 2 is a sectiona view.- on the line -m of Fig/1. Fig. 3' is a transverse sectional y view showing a slight modification. v

this I provide'l'lange'd members, such'as Z- The underframe, hereinafter described in detail, is su ported upon the pedestals over the journaloxes of the car, andto facilitate beams 1 and secure `them upon the pedestals p lf. A center'girder 2 vis disposed between the Z-beams and preferably consists of two channel-iron members spacedapart and having a filler 3 secured between them. This center girder is supported upon the Z-beams h the medium of cross-beams 4. Each .crossearn 4 comprises two members and v each of these members consists of channels '.'either rolled or pressed into cured at their inner ends to shape and sethe respective f, members of the center 'girder an appreciable distance below the up er. flanged e ges of the latter, by means o anvleplates 5. The channel -members of eacln cross-beam rest upon the Z-beams and project so'medista'nce laterally beyond the same. The channel members of the cross-beamsiare of comparatively shallow depthor width and the mem*- bers of the "center girder are provided with slots through which compression plates 6 and tension cross-beammenbers resting u beams and projecting latera Patented sept. e9,` 190s.

sion Van tensionplates being secure by means of rivets respectively, to the upper and lower flanges of the cross-'beam mem ers.

- Those portions of the channel cross-beam'v lmembers which project laterally from the Z-beams afford' seats for the side-sills 8 of the car. Furring stripsl 9 are located upon the cross-beams, preferably over the su port of the latter upon the Z-beams. fu'rring strips 10 are located upon the crossbeams betweenthe `furring strips 9. and the center` girder.' Angle irons 11 are secured to the webs' 'of the cross-beam members directly under the lside-sills 8 and the furring stripsv 9 and I and furring strips are bolted. A smaller -furring trip 12 is bolted upon each member of the c nter girderv and the upper faces of the furring4 strips 12 are madeto' aline with the and to these angleirons said side-sills passing the lower tension plate (plates 7gare passed,-said com resl ther :i1 per faces ofthe furring strips 9 and 10fand y bers, a ower tension late 14 maybe secured to the lower lian es o the center girder members and tothe ase flanges of the Z-bars 1, as shown inr Fig. 3. Having fully described my invention what I claim as new andl desire to secure by Letters ,Patent, is,-

1. A ear underframe` comprising flanged beams adapted to be supported upon the edestals of the car', a center girder, and crossearns, each cross-beam comprising two channel members ofcomparatively narrow' width and secured at their'inner ends to`\tlzc center girder an appreciable distance from the upper and lower edges thereof, said crossbeam members resting yupon the flanged beams, projecting laterally from the latter and affording seats for side-sills.

2. A car underframe comprising flanged beams adapted to be supported upon the pedestals of the car, a centergirder, crosseam members ofcomparatively narrow depth secured at their inner ends to the center girder an appreciable distance from the upper. and lower edges of the latter, said onthe'langed ly therefrom,

compression plates passing through the center girder and secured upon the cross-beam.

members, and tension plates also assing through the center girder and secure tothe lower edges of the cross-beam members.'

3. The combination with flanged beams adapted to be supported upon the pedestals of a car, and a center girder, of a cross-beam comprising two channeled members each secured at its inner end to the center girder an appreciable distance from the top and bottom thereof, compression and tension plates passing through the center .girder and secured to the upper and lower edges ofthe respective cross-beam members, l`said crossbeam members resting upon the flanged beams and projecting'laterally therefrom, side-sills dis osedupon the rojecting ends of the crossearn members, flJxrrlg strips'located on the cross-beam members between beams and projecting latere the side-sills and the center girder, and furring strips secured upon the center girder.

4. The combination with flanged beams adapted to be supported upon the car pedest'als, and a center girder, of cross-beams, each comprising two channel members secured at their inner ends to the center girder, said cross-beam members resting ulpon the iian ged y beyond the same, urring strips located upon the crossbeam members, and angle-irons secured to the cross-beam members and to the furring strips.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

ANTON BECKER.
